The mechanical loader and unloader carries goods from the deck of a steamer direct to the 

 truck for final delivery to the wholesaler. It has a capacity of one ton per minute 



A COMBINED mechanical loader and 

 unloader which will carry packed 

 goods from the deck of a ship direct 

 to the body of the waiting motor vehicle for 

 final delivery to the wholesaler or to the 

 consumer, with but one handling, is designed 

 to materially reduce the final cost of goods 

 to the purchaser 

 by reducing 

 transportation 

 charges. 



The appa- 

 ratus consists of 

 portable sec- 

 tions of belt 

 con V e y o r s 

 mounted on 

 small stands 

 with castor 

 wheels. These 

 are moved 

 about the wharf 

 or freight sta- 

 tion to meet the 

 physical condi- 

 tions existent, 

 and when made 

 into one con- 

 tinuous convey- 

 or will carry any 

 kind of packed 

 goods from any 

 desired point 



to any other in remarkably quick time. 

 The apparatus shown has a capacity of a 

 ton a minute. One unloader is thus able to 

 unload a ship having a carrying tonnage of 

 four thousand in about sixty hours or six 

 days of ten hours each. With two such 

 unloaders the vessel could be unloaded in 

 three days, whereas a crew of perhaps a

hundred men working in day and night 

 shifts would be required to accomplish the 

 same result and at a much greater cost. 



The conveyor sections are simply steel 

 latticed beams carrying endless belts driven 

 by gears through the mediurn of electric 

 current, steam, compressed air, oil under 



pressure or by 

 means of inter- 

 nal combustion 

 engines accord- 

 ing to the mo- 

 t i ve power 

 most available. 

 The power is ap- 

 plied to one of 

 the belt sections 

 and then trans- 

 ferred to the one 

 adjacent to it 

 by means of 

 small sprockets 

 and chains on 

 the sides, as 

 shown in the 

 accompanying 

 illustrations. 



In the case 

 shown , the goods 

 being unloaded 

 travels down a 

 grade from the 

 deck of the ship 

 to the level section on the wharf and then 

 up a twenty per cent incline at the other 

 end directly into the body of the waiting 

 vehicle. If it is not desired to load it 

 directly, it may be stored in piles. The 

 entire operation is performed with but one 

 handling, that of loosening the sling by 

 means of which the bundles are lifted.
